Description

Technical Field

[0001] This utility model relates to the field of bearing technology, and in particular to a wear-resistant self-aligning roller bearing. Background Technology

[0002] Self-aligning roller bearings are a type of bearing. Common self-aligning roller bearings include an outer ring and an inner ring arranged coaxially, and a cage positioned between them. Several rollers are arranged circumferentially in the gap between the inner and outer rings, with one row of rollers on each side of the cage. The cage evenly separates the circumferentially arranged rollers. Existing roller bearings may suffer from insufficient rotational smoothness due to high frictional resistance and unstable roller positioning, affecting the overall performance of the bearing. For example, Chinese patent disclosure "A High Wear-Resistant Self-Aligning Roller Bearing," application number "202322934653.4," describes a method that... An annular pad is installed on the inner wall of the bearing race, allowing the rollers to roll on it. The annular pad is made of chromium-molybdenum steel, which has high hardness and wear resistance, greatly improving the compressive strength and wear resistance of the annular pad and extending its service life. When the annular pad wears out after long-term use, only the new annular pad needs to be replaced, without replacing the entire bearing race, thus avoiding waste. However, although the annular pad design of this device improves wear resistance through the high hardness and wear resistance of chromium-molybdenum steel, relative sliding friction may still exist between the rollers and the annular pad, resulting in greater frictional resistance and affecting the smoothness of bearing rotation. Summary of the Invention

[0003] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a wear-resistant self-aligning roller bearing. By rotating a support ring between the inner and outer rings, and installing ball bearings rotatably connected to the support ring, the frictional resistance between the upper and lower support plates during bearing operation is reduced. At the same time, the upper protective plate, the upper limit rod, and the upper support plate constitute the limiting mechanism for the upper rollers, and the lower protective plate, the lower limit rod, and the lower support plate constitute the limiting mechanism for the lower ball bearings. By adding a ball bearing mechanism inside the roller bearing, the smoothness of bearing rotation is further increased, which is beneficial to improving the wear resistance of the bearing.

[0004] This utility model also provides a wear-resistant self-aligning roller bearing, comprising: an outer ring; an upper protective plate rotatably connected to the inner side wall of the outer ring; an inner ring rotatably connected to the inner side wall of the upper protective plate; an upper limit rod fixedly connected to the lower surface of the upper protective plate; an upper support plate fixedly connected to the lower end of the upper limit rod; upper rollers rotatably connected between the upper limit rods; a lower protective plate rotatably connected to the inner side wall of the outer ring; a lower limit rod fixedly connected to the upper surface of the lower protective plate; lower rollers rotatably connected between the lower limit rods; a lower support plate fixedly connected to the upper end of the lower limit rod; a support ring rotatably connected to the inner side wall of the outer ring; a support shaft rotatably connected inside the support ring; and balls rotatably connected to the side surface of the support shaft. This device improves the wear resistance of the bearing.

[0005] According to the present invention, a wear-resistant self-aligning roller bearing is provided, wherein the inner wall of the outer ring and the outer surface of the inner ring are provided with a rotating groove, and the upper protective plate and the lower protective plate are located inside the rotating groove. The above device is beneficial to the stable operation and protection of the bearing.

[0006] According to the present invention, a wear-resistant self-aligning roller bearing is provided, wherein the upper roller is located between the upper protective plate and the upper support plate, and the lower roller is located between the lower protective plate and the lower support plate. The above device is beneficial to the stability of the roller.

[0007] According to the present invention, a wear-resistant self-aligning roller bearing is provided, wherein the support ring is provided with a limiting hole inside, and both ends of the support shaft are located inside the limiting hole. The above device is beneficial for positioning and limiting the support shaft, thus ensuring its stability.

[0008] According to the present invention, a wear-resistant self-aligning roller bearing is provided, wherein the lower surface of the upper support plate and the upper surface of the lower support plate are both provided with sliding grooves, and the ball is located inside the sliding groove. The above device is beneficial to the smooth rolling of the roller.

[0009] According to the present invention, a wear-resistant self-aligning roller bearing is provided, wherein the upper support plate is located above the lower support plate, and the support shaft, balls and bracket ring are located between the upper support plate and the lower support plate. The above device is beneficial to the stability of the structure.

[0010] According to the present invention, a wear-resistant self-aligning roller bearing is provided, wherein the inner ring is located at the center of the outer ring, and the upper protective plate, upper limit rod, upper roller, upper support plate, bracket ring, support shaft, ball bearing, lower protective plate, lower limit rod, lower roller, and lower support plate are located between the inner ring and the outer ring. The above devices help to ensure the compactness and stability of the structure.

[0011] Compared with existing technologies, this wear-resistant self-aligning roller bearing reduces the frictional resistance between the upper and lower support plates during bearing operation by using a rotating support ring between the inner and outer rings and installing ball bearings rotatably connected to the support shaft inside the support ring. Simultaneously, the upper protective plate, upper limit rod, and upper support plate constitute a limiting mechanism for the upper rollers, while the lower protective plate, lower limit rod, and lower support plate constitute a limiting mechanism for the lower ball bearings. Adding a ball bearing mechanism inside the roller bearing further increases the smoothness of bearing rotation and improves the bearing's wear resistance. Attached Figure Description

[0022] Specifically, the outer ring 1, as the outermost component of the bearing, provides the foundation for the installation and fixation of the entire bearing. The inner ring 2, as the inner structure of the bearing, is fixed to the equipment mounting location through the outer ring 1. The inner ring 2 is installed in conjunction with the rotating shaft. When the shaft rotates, the inner ring 2 rotates accordingly. The upper roller 4 and the lower roller 5 roll on the tracks formed by the upper protective plate 3, the upper support plate 7, the lower protective plate 6, and the lower support plate 8, respectively, converting the sliding friction between the inner ring 2 and the outer ring 1 into rolling friction. The upper protective plate 3 and the lower protective plate 6 play a protective role, preventing impurities from entering the rolling area. The upper support plate 7 and the lower support plate 8 axially position the rollers through the upper limit rod 11 and the lower limit rod 12, ensuring the stable rolling of the rolling elements. At the same time, the components cooperate with each other to jointly bear and transmit the load, realizing the bearing's load-bearing and power transmission functions.

[0023] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The inner wall of the outer ring 1 is rotatably connected to a bracket ring 14. The support ring 14 is rotatably connected to a support shaft 10. The support ring 14 is provided with a limit hole 13. The two ends of the support shaft 10 are located inside the limit hole 13. The side surface of the support shaft 10 is rotatably connected to a ball bearing 9. The lower surface of the upper support plate 7 and the upper surface of the lower support plate 8 are both provided with a sliding groove. The ball bearing 9 is located inside the sliding groove. The upper support plate 7 is located above the lower support plate 8. The support shaft 10, the ball bearing 9 and the bracket ring 14 are located between the upper support plate 7 and the lower support plate 8. The inner ring 2 is located at the center of the outer ring 1. The upper protective plate 3, the upper limit rod 11, the upper roller 4, the upper support plate 7, the bracket ring 14, the support shaft 10, the ball bearing 9, the lower protective plate 6, the lower limit rod 12, the lower roller 5 and the lower support plate 8 are located between the inner ring 2 and the outer ring 1.

[0024] Specifically, the support ring 14 is rotatably connected to the inner side wall of the outer ring 1, and the support shaft 10 is rotatably connected inside the support ring 14. Both ends of the support shaft 10 are located in the limiting holes 13 inside the support ring 14, which restricts the axial movement of the support shaft 10. When the bearing is running, the support ring 14 rotates with the movement of the outer ring 1, and at the same time drives the support shaft 10 and the ball 9 and other components to move together, so as to realize the transmission of load and the stable rolling of the rolling elements. The ball 9 rolls in the grooves of the upper support plate 7 and the lower support plate 8, reducing frictional resistance and increasing the wear resistance of the bearing.

[0025] Working principle: The outer ring 1 serves as the outermost component, providing a foundation for installation and fixation. The inner ring 2, as the inner structure, is fixed to the equipment mounting location via the outer ring 1 and is installed in conjunction with the rotating shaft. When the shaft rotates, the inner ring 2 rotates accordingly. The upper protective plate 3 is rotatably connected to the inner wall of the outer ring 1 and the inner ring 2. Its lower surface is connected to the upper support plate 7 via the upper limit rod 11. The upper roller 4 is rotatably connected between the upper limit rods 11. The lower protective plate 6 is rotatably connected to the inner wall of the outer ring 1. Its upper surface is connected to the lower support plate 8 via the lower limit rod 12. The lower roller 5 is rotatably connected between the lower limit rods 12. The upper and lower rollers roll on the tracks formed by the corresponding protective plates and support plates, thus connecting the inner ring 2 and... The sliding friction between the outer rings 1 is converted into rolling friction. The protective plate can prevent impurities from entering the rolling area. The bracket ring 14 with the limiting hole 13 is rotatably connected to the inner wall of the outer ring 1. The support shaft 10 with both ends located in the limiting hole 13 is rotatably connected inside. The side surface of the support shaft 10 is rotatably connected to the ball 9. The upper and lower support plates are provided with sliding grooves. The ball 9 is located in the sliding grooves. When the bearing is running, the bracket ring 14 rotates with the outer ring 1 and drives the support shaft 10 and the ball 9 to move. The ball 9 rolls in the sliding groove to reduce frictional resistance and increase wear resistance. All components cooperate with each other to jointly bear and transmit loads, realizing the bearing's load-bearing and power transmission functions.
